Illumination device

ABSTRACT

An illumination device. The illumination device generally has at least one light source and an attachment assembly that connects the light source to a computing device. The light source may be one or more LEDs or a light panel using electroluminescent lighting. The illumination device includes a power source coupled to the light source and a light control mechanism to change at least one of an operative state or an intensity of the light source. The illumination device may also be integrally connected to the computing device. A light cover is implemented to cover the light source and diffuse light emanating therefrom.

FIELD OF THE EMBODIMENTS

The invention relates to an illumination device, and more particularlyto an illumination device attached to a computing device, especially ahandheld computing device such as a smart phone, to facilitate videocalls, teleconferences, other camera-related processes, and otherapplications conducted with the computing device requiring optimizedillumination.

BACKGROUND OF THE EMBODIMENTS

Computing devices, especially handheld computing devices, have undergoneexplosive development in the past two decades. Here, computing devicesrefer to but are not limited to: desktop computers, laptop computers,and handheld computing devices such as but not limited to smart phonessuch as iPhones® or Android® phones, computing tablets such as iPad®,Personal Data Assistants (PDAs), and other devices that are relativelysmall and light and are equipped with basic computing and internetconnecting capabilities. Computing devices are playing more and moresignificant roles in people's work, entertainment, and communications.

Most of the computing devices nowadays are equipped with cameras. Inmany cases, especially for handheld computing devices, there are twocameras, one on the front side of the device—the same side with ageneral display screen, and the other one on the back side. One fairlywidespread usage of the computing devices is video call, or videoconference in some instances, during which both video images and audiosignals are transmitted and received. Most likely the video images arecaptured with the front side camera, allowing a user of the device tosee the display on the device and be visible at the same time. Videocalls enable the callers to hear and see the other person at the sametime. Combined with the mobile capacity of the handheld computingdevices, video calls strongly facilitate communication and interactionbetween the parties.

One drawback of the video call conducted on a computing device, however,is the unpredictable and often far-from-ideal illumination, whichrenders the video call less attractive or even impossible to proceed.This problem is especially acute for the handheld computing devices. Dueto their mobility, video calls conducted with handheld computing devicesmay be carried out in some locations never been conceived previously.Instead of a nicely illuminated conference room, a user of a handheldcomputing device may find himself/herself in a car, in a dark room, orin some places with weak or impossible-to-adjust light, making itimpossible to show the user's image properly. The current inventionaddresses this problem by providing an illumination device that may beattached to a computing device and enable a user to have manageablelight for his/her video call or video conference. In addition, theillumination device introduced by the current invention may havenumerous additional applications that would provide significantconvenience and greatly improve the user experience of the computingdevice.

As indicated above, “computing device” used here is a broad concept andit refers to but is not limited to: a desktop computer, a laptopcomputer, and a handheld computing device such as but not limited tosmart phones such as iPhone® or Android® phones, computing tablets suchas iPad®, personal data assistants (PDAs), and other devices that arerelatively small and light and are equipped with basic computing andnetwork connecting capabilities. Since the usage of the presentinvention is more clearly demonstrated on handheld computing devices,the discussions will be focusing on such devices. However, it should beclear that the illumination device disclosed here may also beimplemented to desktop and laptop computers and have significantbeneficial effects.

With the implementation of front and back cameras, handheld computingdevices may be used in ways that could not be conceived before. Asindicated above, one of the applications is video call or videoconference that allows the users to see and speak to one another at thesame time. In most cases, a user is holding the handheld computingdevice with the front of the handheld computing device, defined as theside having a display screen, facing the user. The front camera, thecamera on the same side as the display screen, is thus capable ofcapturing the image of the user, especially the image of the user'sface. Through its networking capacities, the handheld computing devicetransfers the captured image, as well as audio signals recorded, to theother party/parties engaged in the video call or video conference.

Such a communication experience, however, may be spoiled by weak orimproper lighting. When it is too dark, it is very difficult for thefront camera to capture a usable image of the user, making a video callless attractive. Moreover, many other camera-related processes andapplications conducted with a handheld computing device may have similarrequirements for optimized lighting conditions. One simple example istaking a photograph or video recording with the handheld computingdevice, either of the user himself/herself, or of another person, or ofany other scene or subject. When the ambient light is too weak, it mayruin the results of the picture or the video. Another example is the“mirror” application for handheld computing devices, with which a usermay see his/her own image in the display. Poor ambient light conditionsalso harm the usage of such applications.

The current device addresses the problems listed above by attaching alight source, preferably a plurality of light-emitting diodes (LEDs) tothe handheld computing device, allowing the light source to illuminatethe user, especially the user's face, enabling the front camera or theback camera to capture an optimized image of the user or any othersubject and facilitate the video call, the photo or video capturing, the“mirror” application, or any other camera-related experience.

Moreover, with the basic design, there may be numerous variations thatwould provide different kinds of embodiments of the illumination deviceto satisfy different needs for applications and users. Some of theapplications do not even have to be camera-related because theillumination device disclosed herein may also have signaling capacitiesbesides the functions to provide lighting.

The light source, as suggested, is preferably LED lights. However, thelight source may also be other lights such as compact florescent lights(CFL) or electroluminescent light. In particular, electroluminescentlight using algae-based wire and panels, such as the light based on RILItechnology, may be incorporated as the light source in the currentdevice. In addition, sometimes it is desirable to make the lightsadjustable in terms of luminous intensity, viewing angles, anddiffusion. The lights may have color either by using color lights orwith the addition of a color cover. In general, implementing moreadjustability may allow the illumination device to provide lighting forone or more persons and for various purposes. It may also enable theillumination device to flash, to demonstrate different patterns, andtherefore satisfy different needs.

There may be a power source, separate from the power source for thehandheld computing device. The power source may be connected to thelights through a power connector, providing energy needed for theillumination. The power source may be one or more batteries, such as theregular AAA zinc-carbon or alkaline battery, or any other type or sizethat may fit the needs in terms of energy needs or physicalaccommodation. The battery may be disposable or rechargeable, allowingflexibility as to cost-effectiveness and convenience. The battery may beconnected to both the illumination device and the handheld computingdevice, providing energy to both devices, serving as a backup or extrapower source to the handheld computing device. On the other hand, it isalso possible to simply connect the light source to the handheldcomputing device and allow the light source to use the power of thehandheld computing device, reducing the size and weight of theillumination device and making it more portable.

The illumination device includes an attachment assembly that affixes thelight source to the handheld computing device. The attachment ispreferred to be non-permanent, so that the lights may be added orremoved as the user desires. The attachment assembly may take manyforms. For example, it may be a flat case with an indentation to enclosea power source and power connector, while also having a recess ordocking place for the handheld computing device to attach. The currentinvention encompasses all kinds of attachment assemblies that allowconvenient connection between the lights and the handheld computingdevice. Moreover, the attachment assembly may serve additional purposessuch as supporting the handheld computing device in an easy-to-viewposition, allowing a user of the handheld computing device to watch thedevice in a hand-free mode. In addition, more complex attachmentassembly may include structures that allow the illumination device to befurther integrated with the handheld computing device in terms ofsynergetic control and data sharing.

The illumination device may further comprise an external switch thatallows the user to turn the lights on and off. However, it is possible,especially when the illumination device is sufficiently integrated withthe handheld computing device, to use the buttons, switches, and menuson the handheld computing device to control the lights.

As indicated above, the illumination device may be used to facilitatevideo calls or video conferences or to enhance other camera relatedfunctions of the handheld computing device. In such a case, theillumination device taught by the current invention may enhance suchexperiences by providing additional and well-controlled illumination.

In addition, with further connection between the lights and the handheldcomputing device, the lights of the illumination device may serve asindicators for a handheld computing device's status or as signals forthe applications being used on the handheld computing device. Forexample, the lights may flash or light up when there is an incomingcall. Or the lights may change in lighting pattern, luminous intensity,or color when the user is speaking on the handheld computing device orwhen certain music or game is being played.

Also in the purview of the current invention is a series of computerprograms or applications that may be used to control the illuminationdevice. For example, a basic version of such a program would be able toadjust the luminous intensity, viewing angles, lighting pattern, and/orcolor of the illumination device. A more advanced program would allowthe illumination device to synergize with the status of the handheldcomputing device, such as an incoming phone call. Still another advancedprogram may integrate the illumination device with another applicationso that the lights are partially controlled by the application.

In general, the illumination device is designed to be small, portable,versatile, energy efficient, durable, and fully compatible with thehandheld computing device, or more generally, the computing device, thatis to be used with the illumination device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The preferred embodiments of the present invention will now be describedwith reference to the drawings. Identical elements in the variousfigures are identified with the same reference numerals.

Reference will now be made in detail to embodiment of the presentinvention. Such embodiments are provided by way of explanation of thepresent invention, which is not intended to be limited thereto. In fact,those of ordinary skill in the art may appreciate upon reading thepresent specification and viewing the present drawings that variousmodifications and variations can be made thereto.

FIG. 1 is an isometric drawing of a front view of a first embodiment ofthe present invention when an illumination device is connected to ahandheld computing device. Shown in FIG. 1 are the illumination device 1attached to the handheld computing device 100, wherein the illuminationdevice 1 comprises an attachment assembly, which here manifests itselfas a case 55, a power source 30, a dock 60 for the handheld computingdevice 100, an illumination device switch 70, and a light sourcecomprising a plurality of LEDs. For clarity purposes, not all the LEDsare marked in FIG. 1. Shown in FIG. 1 is also the handheld computingdevice 100 having a display screen 130 defining a front side 110, an ONbutton 170, an OFF button 180, a MENU switch 190, and a front camera120. Also shown in FIG. 1 is an image 140 being displayed in the displayscreen 130.

As indicated above, the handheld computing device 100 is definedbroadly. In FIG. 1, the handheld computing device 100 is shown as asmart phone having a display screen 130, an ON button 170, an OFF button180, and a MENU switch 190. However, it should be clear that the currentinvention may be used to accommodate any computing device by makingcertain adjustments to the power source 30, the case 55 and the dock 60.Moreover, the format and configuration of the handheld computing device100 may vary significantly due to the brand and version of the device.It is very likely that a handheld computing device 100 does not have anyof the buttons or switches shown in FIG. 1. Nevertheless, it should beclear that the current invention provides an illumination device 1 thatmay accommodate all kinds of computing devices, especially handheldcomputing devices.

The image 140 here in FIG. 1 is shown to demonstrate possible display onthe screen when the handheld computing device is in use. The image 140may be the image of a party engaged in a video call or video conferencewith the user of the handheld computing device. The image 140 may alsobe the image of the user of the handheld computing device when aphotograph or video is being captured by the front camera. When it isthe image of the user of the handheld computing device, the user mayview the image and adjust the luminous intensity, viewing angles, color,and lighting pattern of the light source 10 to achieve optimized result.The user may also adjust the distance from the handheld computing device100. The illumination of user with the device will work best when theproper distance from camera to user is achieved. The image 140 may alsobe the image of any person or subject being captured by a camera otherthan the front camera. Furthermore, the image 140 may also serve as anillustration of any picture or image that are displayed on the screen130.

The LEDs, as shown in FIG. 1, are the preferred type of light source 10.As indicated above, it is still possible to use other kinds of light,such as CFL or electroluminescent light, as the light source 10. Thebasic features of the LEDs may vary according the specific needs of theuser and the specific usage for the illumination device 1. For example,the LEDs' luminous intensity, viewing angle, and color may be differentfrom model to model. It is possible to use LED emitting white light orcolor lights. It is also possible to use color covers or films to enablea white-light LED to show color. Preferably, a plurality of LEDs areused as the light source 10, as shown in FIG. 1. However, it is possibleto use only one light. The LEDs may be controlled individually or as awhole regarding switching them on or off, or regarding the luminousintensity, viewing angle, and color of the LEDs. Alternatively, the LEDsmay be arranged into subsections that may be controlled as individualsubsections. For example, as in FIG. 1, the LEDs may be arranged intothree subsections: the left four LEDs, the right four LEDs, and the toptwo LEDs. As a user of the handheld computing device 100 desires, he/shemay choose to turn on and off any subsection or change the features ofany subsection according to the ambient light conditions, the posture ofthe user, and/or the application or process involved.

The LEDs may have different technical specifications and dimensions. Ingeneral, the LEDs should be small and match the handheld computingdevice 100 and the intended usage. Standard T1 LEDs, T1-3/4 LEDs,various kinds of surface mount LEDs, miniature LEDs, mid-range LEDs,high-power LEDs, LED panels, LED modules, and other kinds of LEDs mayall be possible choices for specific uses. Some special types of LEDsmay be used for special effects.

For example, single wave length LEDs may be used to light therapy. Ingeneral, the LEDs may use electricity ranging from 0.1 mW to 50 W, withcurrent ranging from 0.1 .mu.A to 1 A and voltage ranging from 0.1 mV to250 V. The LEDs may emit white light or color light with particularwavelengths. In a preferred embodiment, the LEDs emit light of warmcolor temperature, i.e. 2400 Kelvin.

The power source 30 here in FIG. 1 is not an indispensable component ofthe illumination device 1. In some situations it is preferable to have apower source 30 as shown in FIG. 1. However, in other situations, havinga power source presents different advantages. For example, when theillumination device 1 is equipped with a connector to the internal powersource of the handheld computing device 100, it is possible for theillumination device 1 to share the power source with the handheldcomputing device 100, making the structure of the illumination device 1less complicated and easier to control. However, when it is desirable tohave a long battery life or to have a changeable illumination device 1that may fit different kinds of handheld computing device 100, it isprobably advantageous to have an power source, like the power source 30shown in FIG. 1, because the power connector may not fit with all thedifferent handheld computing devices.

In FIG. 1, the power source 30 may be a battery. However, it may well beother kinds of power sources as long as the light source 10 is providedwith energy. If a battery is used, the power source 30 may be adisposable battery or a rechargeable battery, addressing differentconcerns such as cost and convenience. In terms of chemical composition,many kinds of batteries may be used. The types of batteries to be usedas the power source 30 include but are not limited to: zinc-carbonbatteries, alkaline batteries, aluminum batteries, dry-cell batteries,lead-acid batteries, lithium batteries, nickel batteries, potassiumbatteries, and sodium-ion batteries.

The power source 30 is designed to provide power to the LEDs. When thevoltage or current provided by the power source 30 is insufficient topower the LEDs, it is possible to include a regulator circuit, such as abuck-boost converter, to enhance the output from the power source andensure that the LEDs are adequately supplied. Such regulator circuitsare well-known in the arts. In addition, the illumination device 1 mayfurther comprise a battery meter that measures the battery life andinforms the user to change batteries when necessary. The technology forsuch battery meter is also well known in the arts.

In addition to providing power to the LEDs, the power source 30 mayserve as a backup power source to the handheld computing device 100.With proper connections between the handheld computing device 100 andthe illumination device 1, both in terms of control circuitry andelectricity connections, it is possible that the power source 30 may beused to directly provide energy to the handheld computing device 100,enabling a longer overall battery life and providing more flexibility.When the power source 30 is rechargeable, the handheld computer device100 may also be recharged, enabling a convenient solution for supplyingpower to both the illumination device 1 and the handheld computingdevice 100.

It should be noted that FIG. 1 is only supposed to be illustrative as tothe position and arrangement of the case 55 and the power source 30. Thepower source 30 may be located at other positions. For example, thepower source 30 may be shield in a chamber attached to the back of thecase 55.

In FIG. 1, an illumination device switch 70 is also shown. Such anexternal switch, as a power source 30, is not an indispensable part ofthe illumination device 1. If the illumination device 1 is sufficientlyintegrated with the handheld computing device 100, it is possible tocontrol all aspects of the LEDs through the buttons, menus, and switchesof the handheld computing device 100. Such a design may also provide afull spectrum of options as to the individual, sub-sectional, or wholegroup of LEDs' luminous intensity, viewing angle, color, and lightingpatterns. However, in certain situations, having an external switch maybe desirable because it affords a quick and easily accessible controlfor the lights.

It should be noted that the switch 70 may have different designs toaccommodate different needs. The switch 70 may be mechanical, electricalor logical. In its most simple form, switch 70 may turn on and off allthe LEDs without any other adjusting capacities. However, switch 70 mayalso be designed as a dimmer that dictates the brightness, or luminousintensity of the LEDs in a certain range. One possible design is thatthe switch 70 may control mechanical means of adjustment such asarticulating lens or lenses covering the LEDs, allowing for change ofillumination intensity. To enable the switch 70 to perform such afunction, some well know circuits such as a potentiometer may beincluded in the illumination device. Moreover, switch 70 may have a morecomplex design to control the individual, sub-sectional, or whole groupof LEDs' luminous intensity, viewing angle, color, and lightingpatterns.

The current invention discloses an attachment assembly that affixes alight source 10 to a computing device. In the embodiment shown in FIG.1, while the computing device is a handheld computing device 100, theattachment assembly is a case 55 having a recess that partially encasesthe handheld computing device 100, leaving the front side 110 largelyexposed so that the display screen 130 may be viewed clearly and thefront camera 120 may be unblocked. The handheld computing device 100 issnapped in the recess of the case 55. The LEDs are mounted on the edgesof the case 55 to direct light from the LEDs in a generallyperpendicular direction to the front side 110 of the handheld computingdevice 100.

The case 55 may be a one-piece structure or have a multi-piece designfor more flexibility and convenience. In addition to attaching the lightsource 10 to the handheld computing device 100, the case 55 may alsoprovide physical and hygienic protection to the handheld computingdevice 100, preventing it from damages due to physical impact. The case55 may be made from materials such as but not limited to: rubber,leather, wood, marble, artificial stone (e.g., Silestone®), graphite(e.g., carbon fiber), metal sheet or foil, or plastic such as, but notlimited to, polyethylene terephthalate (PET), polyethylene (PE),high-density polyethylene, polyvinyl chloride (PVC), polyvinylidenechloride (PVDC), low-density polyethylene (LDPE), polypropylene (PP),polystyrene (PS), high impact polystyrene (HIPS) and polycarbonate (PC),or some combination thereof. The case 55 may be made of one kind ofmaterials, or different parts of the case 55 may be made of differentmaterials, ensuring optimized protection and feel.

It should be noted that the “snap-in” design is not the only form ofattachment to connect the handheld computing device 100 to the case 55.For example, the case 55 may comprise two pieces of cover, either orboth may be slidably connected to the handheld computing device 100. Itis also possible that the handheld computing device 100 may be fastenedto the case with other means such as pre-positions screws, hook-and-loopfastener, riveting, or any other kind of mechanisms allowing a secureattachment. Preferably, the case 55 is removably attached to thehandheld computing device 100, allowing easy detaching for higher levelof flexibility. However, it would also be acceptable to make the case 55a permanent fixture of the handheld computing device 100, allowing highlevel of integration between the handheld computing device 100 and theillumination device 1.

The LEDs may be mounted to the case 55 by any means that allow secureattachment. The LEDs may be welded, screwed, riveted, glued, co-molded,or in any other way linked to or inserted into the case 55. Necessarystructures, such as prepositioned magnets or hook-and-loop fasteners, orsnaps, may be employed to fasten the LEDs to the case 55. In general,the LEDs may be connected to the case 55 in a permanent or removablemanner. Moreover, the approach to connect the LEDs to the case may varydue to the type of LEDs or the type of cases used.

After attachment, the relative positions and the projection angles ofthe LEDs may still be adjustable, allowing more flexibility as to thearea, scope, and depth of illumination. Moreover, the attachment methodfor the LEDs may be designed in such a way that allows the LEDs toilluminate to a direction not generally perpendicular to the front sidethe handheld computing device. For example, each LEDs may be mounted onthe case with a universal wheel that allows the LED to tilt to alldirections. Thus, when it is desirable to use the LEDs with the backcamera of the handheld computing device, such designs may allow the LEDsto illuminate in the direction of the back camera.

As indicated above, the attachment assembly may take other forms apartfrom a case 55. The key is to enable the attachment assembly to attachthe light source 10 to the handheld computing device. In the simplestformat, the light source 10 may be mounted directly on the handheldcomputing device, making the light source 10 integral to the handheldcomputing device. In that case, the attachment assembly may simplycomprise the minimum material or structure, such as the magnet, glue,screw, rivet, or welding material that connects the light source 10 tothe handheld computing device. In a more complex form, the attachmentassembly may comprise simply of one or more attachment strips that havethe LEDs mounted on the strips and these strips may be attached to thehandheld computing device through any means possible. The strips may beconnected to the handheld computing device with screws or hinges,allowing the strips to tilt away from the handheld computing devicewhile maintaining the attachment, enabling the LEDs to illuminate awider area. When necessary, the LEDs may even be removed from thehandheld computing device and the attachment assembly may comprise anextension cord that allow the LEDs to be powered, controlled, andprovide illumination to an extended area. Such a design may be helpfulto maximize the illumination scope of the illumination device.

The illumination device 1 may further comprise a sensor that detects andmeasures ambient light conditions. The general structure and circuitryfor such sensor is well known in the arts. An ambient light sensor (seeFIG. 7) may facilitate the adjustment process for the luminousintensity, viewing angle, color, and lighting pattern of the handheldcomputing device, making it possible for automatic control when anapplicable computer program is installed.

FIG. 2 is an isometric drawing of a side view of the first embodiment ofthe present invention when an illumination device is connected to ahandheld computing device. To make the various elements visible, dottedlines are used to illustrate structures that are shielded from view bythe case 55. Shown in FIG. 2 is the illumination device 1 having a case55, a power source 30, a dock 60, a plurality of LEDs covered by lightcovers 20, and power connector 40 connecting the LEDs to the powersource 30. Also shown in FIG. 2 is the handheld computing device 100being encased in the case 55. For clarity purposes, not all the LEDs orlight covers are marked in FIG. 2.

The power connector 40 represents a means to connect the LEDs to a powersource, such as the power source 30 shown in FIG. 2. As indicated above,the power source 30 may be a battery or any other kind of power sourcethat is compact and safe. The power connector 40 may be regular electricwiring that is well-known in the arts or any other kinds of circuitrythat may be used to connect a light source 10 to a power supply.

The dock 60 may be considered a part of the attachment assembly,together with the case. Like the power connector 40, the dock 60 is notan indispensable structure of the illumination device. However, the dock60 may play some important roles if it is present. The dock 60 may serveas part of the “snap-in” structure that secures the handheld computingdevice 100 in the case 55. More importantly, the dock 60 may includeconnectors that may be plugged into the handheld computing device 100and serve to integrate the illumination device 1 with the handheldcomputing device in terms of data sharing, synergistic control, andsharing of power sources. The technology to enable the dock 60 to serveas a connector to the handheld computing device 100 is well known in thearts.

The light covers 20 may be a lens used to diffuse the light from theLEDs, focus the lights from the LEDs, and/or add certain colors when theLED light is white. The light cover 20 may diffuse and soften the lightfrom the LEDs and help to achieve optimal illumination without creatinga blind effect.

The light cover 20 may be any kind of diffuser, such as but not limitedto: polycarbonate LED diffuser, acrylic LED diffuser, clear LEDdiffuser, opal LED diffuser, satin LED diffuser, LED diffuser films, orany product or material having LED light diffusing capability. The lightcovers 20 may also be any kind of lens that is adjustable orunadjustable. The light covers 20 may be colored, changing white lightemitted by the LEDs to color lights.

The light covers 20 may be attached to the LEDs or to the case. Themanner of attachment may vary according to the materials used and thespecific configuration of the different structures. The light covers 20may be slidable or rolling covers that may be attached or detachedeasily. The light covers 20 also be glued, screwed, welded, or rivetedto the LEDs or the attachment assembly.

The configuration of the light covers 20 may differ from what is shownin FIG. 2. For example, the light covers 20 may take the form of “lightstrip” or a “light pipe,” which may cover more than one LED light. Inparticular, one “light pipe” may cover the left four LEDs, another onefor the right four LEDs, and another for the two LEDs on top, enablingbetter diffusion and better illumination. Alternatively, a continuous“light strip” or “light pipe” may cover all the LED lights.

FIG. 3 is an isometric drawing of a back view of the first embodiment ofthe present invention when an illumination device is connected to ahandheld computing device. Shown in FIG. 3 are the case 55, the LEDs,and the handheld computing device 100 having a back side 115 and a backcamera 125 on the back side 115.

As indicated above, the attachment assembly may take many forms. Thecase 55 here is one example that allows both light source 10 attachmentand general protection to the handheld computing device. Certain methodsto mount the light source 10 to the case may allow the light source 10,preferably LEDs, to be adjustable in position and used with the backcamera 125. In such circumstances, the LEDs may assist the photo orvideo capturing process or other applications conducted with the backcamera.

The attachment assembly may also comprise other structures that may becombined with the case 55. One possible addition is a hand-freestructure such as but not limited to a frame stand and/or a hanger. Theframe stand or hanger is preferably foldable and may attach to the backof the case 55, occupying little space with folded. When the frame standor hanger is unfolded, it may support or hang the handheld computingdevice in an upright position, allowing the display to be viewedcomfortably by a user without occupying a user's hand. Moreparticularly, the side(s) and bottom edge of the case may be able to bemade with an angled surface so that the case may serve as part of astand. For example, the thicker bottom area in a case, adjacent to wherethe external battery is installed, may provide enough surface to supportan IPhone® at an angle. In summary, the frame stand or hanger enableshand-free viewing of the handheld computing device, providing moreflexibility as to what can be done with the device.

FIG. 4 is an isometric drawing of a front view of a second embodiment ofthe present invention when an illumination device is connected to ahandheld computing device. Shown in FIG. 4 are the illumination device 1attached to a handheld computing device 100, wherein the illuminationdevice 1 comprises an attachment assembly, which comprises a case 55 anda dock 60, and a plurality of LEDs. For clarity purposes, not all theLEDs are marked in FIG. 4. Shown in FIG. 4 is also the handheldcomputing device 100 having a display screen 130 defining a front side110, an ON button 170, an OFF button 180, a MENU switch 190, and a frontcamera 120. Also shown in FIG. 4 is an image 140 being displayed in thedisplay screen 130.

FIG. 5 is an isometric drawing of a side view of the second embodimentof the present invention when an illumination device is connected to ahandheld computing device. To make the various elements visible, dottedlines are used to illustrate structures that are shielded from view bythe case 55. Shown in FIG. 5 is the illumination device 1 having a case55 and a dock 60, a plurality of LEDs covered by light covers 20, and apower connector 40. Also shown in FIG. 5 is the handheld computingdevice 100 being encased in the case 55. For clarity purposes, not allthe LEDs or light covers are marked in FIG. 5.

FIG. 4 and FIG. 5 illustrate a second embodiment of the currentinvention. In this embodiment, the power source and the switch shown inFIG. 1-2 are no longer present. The light source 10, here a plurality ofLEDs, is connected by the power connector 40 to the internal powersource of the handheld computing device 100. Moreover, with furtherintegration of the illumination device 1 and the handheld computingdevice 100, the luminous intensity, viewing angle, color, and lightpattern of the light source 10 may be adjusted by the switches, buttons,and menus of the handheld computing device, eliminating the need for anexternal control switch. Such a design simplifies the basic structure ofthe illumination device 1, yet requiring higher level of connection andsynergy between the illumination device 1 and the handheld computingdevice.

It should be noted that the second and third embodiments may notnecessarily be described to the fullest extent because such descriptionsare provided for the first embodiment. In particular, the descriptionfor any of the embodiments should be considered included otherembodiments as long as there is not conflict between the descriptions.

FIG. 6 is an isometric drawing of a front view of a third embodiment ofthe present invention when an illumination device is connected to ahandheld computing device. Shown in FIG. 6 are the illumination device 1attached to the handheld computing device 100, wherein the illuminationdevice 1 comprises a light source 10 comprising a circular light panel200 encircling a display screen 130. Shown in FIG. 6 is also thehandheld computing device 100 having a display screen 130 defining afront side 110, a MENU switch 190, and the front camera 120. Also shownin FIG. 6 is an image 140 being displayed in the display screen 130.

In the third embodiment, some other features such as the attachmentassembly, the power source 30, the dock 60, and the illumination deviceswitch 70 are not displayed. However, it should be noted that thesestructures may still be present, but shielded from direct view. Asindicated above, electroluminescent light using algae-based wire andpanels, such as the light based on RiLi technology (produced byRevolution in Lighting, Inc.), may be used as the light so urce 10. Thedesign of the circular light panel 200 is particularly suitable to usesuch lighting technology, which is in general energy efficient, longlasting, bright, and having a wide viewing angle. The circular lightpanel 200 is preferably thin and may attach to the handheld computingdevice 200 using an attachment assembly comprising any kind ofconnecting mechanism, such as industrial glue. It should also be notedthat the design, size, and shape of the light panel 200 may varyaccording to functional and/or aesthetic needs. The power supply, thecontrol system, and the possible varying display of lighting by thelight source 10 are fully described above and below.

Referring now to FIGS. 7 and 8, there is another embodiment of thepresent invention as shown from the front and back, respectively. Theillumination device 1 takes the form of a case 55 and is shown without acomputing device 100 (see FIG. 15) attached thereto. Generally, theembodiment has a front side 110, back side 115, top 105, bottom 95, andat least two side surfaces 90. Each of these surfaces interact togenerally define a recess 65 as shown in FIG. 7.

Each of the side surfaces 90 has a generally horizontal extension orlight rail that extends past and from the front surface 110. The lightrails generally comprise a light cover 20 and a plurality of lightsources or LEDs. The plurality of light source 10 are preferably LEDsthat emit white light. The white light can be produced via mixed-colorlighting or phosphor conversion or any other suitable technology. Insome instances, it may be desirable to have the LEDs be capable ofproducing different colors and/or differing shades of light and suchLEDs may be incorporated as appropriate. The light source 10 may be anytype of LEDs as previously described herein and are preferably surfacemounted LEDs, or may alternatively be any other suitable type of lightsource, such as, without limitation incandescent, fluorescent, orhigh-intensity discharge (HID) bulbs.

The light covers 20, here, are coverings for the LEDs. The light covers20 may cover, but not touch, each light source 10 individually or covera number of light source 10 simultaneously. In other embodiments, thelight covers 20 may cover, and touch, any one or more light sources 10.The light covers 20 are preferably translucent, and in some casestransparent, plastic coverings that serve to diffuse the light as itpasses through these coverings. The light coverings 20 may be removableand may comprise different materials and colors to provide a particulardegree of diffusion or a tint, shade, or other color distortion or anycombination thereof to the light source 10. In other embodiments, thelight covers 20 are permanently attached thereto.

Further, each of the light covers 20 are designed to permit light to beemitted outwards from the illumination device 1 along at least a 180°arc. This is due to the fact the light covers 20 are generally shaped tocover the area above the light source 10 and on each side of the lightsource 10 to the point at which the light source 10 terminate at thedevice. In some instances, the light covers 20 may further be disposedpast the point of termination of the light source 10 and may allow forrear facing light source 10 using the same principles as the frontfacing light sources described herein.

The light covers 20 are preferably disposed along the length of the sidesurface(s) 90, but may fully encircle the case 55. The light covers 20may also be intermittent with gaps or spaces in between a number ofseparate light covers. In a preferred configuration, one light rail islonger than the other light rail (see FIG. 10). This serves to provideaccess to features of a computing device, such as a smart phone, whichare typically disposed on the left-side of the device.

Where the light covers 20 intersect with the top area and bottom area ofthe illumination device 1 a securement mechanism 75 is formed extendingtherefrom. This securement mechanism 75 may be located in at least onecorner area and up to four or more corner areas. In a preferredembodiment, there are at least two securement mechanisms 75. Thesecurement mechanism 75 manifests itself as a tab or extension thatextends substantially perpendicularly from the top of the light cover20. Preferably, the securement mechanisms 75 are disposed on oppositeends and opposite sides of the illumination device 1. This enables, forexample, one securement mechanism to be disposed on the upper left sideand the other to be disposed on the lower right side. This disparityprovides the most secure arrangement of the two form securementmechanism. With three or more securement mechanisms, the arrangement isless vital as the extra points of contact override the necessity for aparticular arrangement.

When a computing device is pushed downward into the recess thesecurement mechanisms 75 slide over a surface of the computing devicethereby securing the position of and retaining the computing devicetherein. In order to remove the computing device, the case 55 is flexeddownwards (away from the computing device) slightly, allowing thesecurement mechanisms 75 to withdraw or recede from covering thecomputing device and the computing device is subsequently removed.

Further features of the illumination device 1 include an aperture 135 toprovide unrestricted or uninhibited access for a rear facing camera ofthe computing device. The position of the aperture 135 can be varied toaccommodate any number of sizes, shapes, and positions. An ambient lightsensor 145 may be disposed thereon to automatically adjust the intensityof the light sources 10 in accordance with the ambient light. A chargingport 85 enables charging of the power source 30 (see FIG. 1) which is arechargeable power source and may be located within the illuminationdevice itself.

In addition, the illumination device 1 may provide for at least onedepressible or touch sensitive button 80. In a preferred embodiment thisbutton is located on the back side 115 of the illumination device 1. Thetouch sensitive button 80 controls an operative state of the lightsources 10. This may include powering the light sources 10 on or off aswell as serving to dim or intensify the light sources 10 as needed.

In order to dim or intensify the light sources 10 one would depress andcontinue to apply pressure to or leave their finger remaining over thebutton area. This action causes the light sources 10 to either dim orintensify until the button is ceased to have been engaged. Furtherengagement of the button 80 will result in further dimming orintensifying based on the current setting of the light sources 10.

In FIGS. 9-12, the embodiment shown in FIGS. 7-8 is further shown fromthe right side, left side, top, and bottom, respectively. Here, theoverall, shape and structure of the illumination device 1 is moreapparent, as are the interactions between the front side 110, back side115, top 105, bottom 95, and sides 90. The light sources 10 are shownfrom one configuration arrangement.

There may be cutouts or voids 150 between areas of the light rails wheresuch voids or spaces 150 have been strategically placed to enableinteraction with the computing device once the computing device has beensecured thereto. As shown, such voids 150 are shown along the top,bottom, and mid to upper left side of the case. These positions are thetypical locations of buttons and other interactive features of computingdevices, namely smart phones. However, the exact arrangement, size, andshape of such voids 150 can be altered as necessary.

As shown in FIG. 12, the charging port 85 is typically located in thebottom of the illumination device 1. The charging port 85 may be anytype of suitable port including those known in the art such as auniversal serial bus (USB) port, which provides for both chargingdownstream ports and dedicated charging ports and other suitablecharging technology. The port is operably coupled to the power sourcecontained therein to charge it as required.

Referring now to FIG. 13, the light covers 20 have been partiallyremoved to expose the light sources 10 thereunder. This arrangement andnumber of light sources 10 is one of but innumerable such arrangementsand is intended to be merely representative of one such arrangement. Itcan also be seen how one of the light rails (left light rail in thisembodiment) contains more light sources 10 and is longer in length thanthe other light rail (right light rail in this embodiment). In otherembodiments, the configuration as to which is the longer light railcontaining more light sources 10 and which is the shorter light railcontaining fewer light sources 10 may be reversed. As should beunderstood, the number of light sources on each rail and the length ofeach rail may be varied as may be desired in order to contain any numberand/or arrangement of light sources 10 on each rail, and the length ofeach rail may also be varied so as to be longer or shorter in length, asdesired.

FIG. 14 demonstrates an iteration of the present disclosure as shownfrom a cutaway sectional view from the view in FIG. 12. As shown, thereis generally a front side 110, a back side 115, and a side surface 90which service to form the recess 65 for receiving a computing device.Emanating or rising from the front side 110 is the light covers 20. Thelight covers 20, as shown, as generally as an inverted “u”-shaped, butmay bear a more rounded “c” or other shape depending on the light source10 used and the preferences for diffusing that light source 10.

The light covers 20 are generally unitary, single channels that runalong either side, or top or bottom of the front side 110. The lightcovers 20 may be disposed separately or may be connected forming acontinuous cover traveling the length of the perimeter. In someembodiments the light covers 20 may be oriented to be positioned alongthe back side 115 as well. The light covers 20, as previously noted, areconfigured to diffuse light. Such diffusion may be accomplished by useof certain materials, textures, patterns, or the like or any combinationthereof comprising the light covers 20. For example, denser materialsare typically more efficient in diffusing light and such a material maybe required with more luminous light sources.

Internally, a printed circuit board (PCB) 160 is shown with arechargeable power source 30 coupled thereto. Power connectors 40, suchas wiring, couples the light sources 10 to the power source. Thedepressible button 80 can function to alter an operative state of thelight sources 10 including to turn light sources on/off as well aschange the luminous output of the light sources 10.

In FIG. 15, the illumination device 1 is shown from a perspective viewwith the computing device 100 removably coupled thereto. The computingdevice 100 has a display screen 130, front facing camera 120, andcomputing device controls 155, and other not explicitly named features.By partially surrounding the computing device with diffused light fromthe light sources 10 and light covers 20, the present invention enableseven and consistent lighting across a subject thereby creating desirablecaptures of static and time varying images as further described herein.

Further, as shown in FIG. 15, the light sources 10 are positionedequidistant from one another. The spacing or gap between these lightsources 10 may vary but is preferably about 0.1 inch to about 2 inches,and more preferably about 0.25 inches. The gap or spacing being definedas the area where the placement of one light source ends and anotherbegins. The light sources 10 may reside on a strip that operably coupleseach light to one another or may otherwise reside directly on theprinted circuit board as described. Other functional implementations mayalso be employed and are covered under the purview of this invention.

In some instances, the general concept described herein in FIGS. 7-14may be capable of being used with a rear facing camera as well. In suchan embodiment, the orientation of the light rails including the lightsources and light covers would be rear facing instead of forward facing.The recess, securement mechanisms, apertures, and the like wouldrelatively stay in the same orientation as with a forward facingimplementation. In some embodiments, there may be both forward facingand rear facing light rails containing light sources and light covers asdescribed herein. In such an embodiment, the light sources (forwardfacing and rear facing) may be able to be independently controlled thusenabling the rear facing light sources to be turned on/off as necessaryand enabling the same functionality to occur with the forward facinglight sources.

As indicated above, it is in the purview of the current invention, asdescribed in the Figures, that a series of computer applications orprograms may accompany the illumination device disclosed herein. Theseapplications may facilitate the use of the illumination device andensure that it is safe, well-controlled, and optimized to assist the useof some other applications. However, it is of note that this is not arequirement and, in fact, it may be more practical to operate thepresent invention as a standalone embodiment. This gives full controlover the illumination device 1 to the user. The user can couple theillumination device 1 to a computing device 100 as needed.

Once coupled to the computing device 100, the user can change theintensity or any other property of the light sources 10 by usingcontrols, switches, and the like embedded with the illumination device 1itself. Further, this standalone usage is enhanced by the rechargeablepower source contained within the case 55. Thus, the power source may berecharged as necessary without requiring the computing device 100 to berecharged, nor would it drain a charge from the power source of thecomputing device.

Referring next to FIG. 16A-FIG. 24F, additional example embodiments ofillumination device 1 are described. It should be noted that theseembodiments may not necessarily be described to the fullest extentbecause such descriptions are provided for in the embodiments describedabove. In particular, the description for any of the embodiments shouldbe considered included in other embodiments as long as there is notconflict between the descriptions

As discussed above, the general concept described in FIGS. 7-14 may becapable of being used with a rear facing camera. Also, in someembodiments, there may be both forward facing and rear facing lightrails containing light sources and light covers. FIG. 16A-FIG. 17Dillustrate example arrangements of case 55 having both forward facingand rear facing light rails containing respective light sources 10, 210and respective light covers 20, 220, which may be used with both forwardfacing and rear facing cameras. The type, arrangement, configuration,location and number of light sources 10, 210 is one of but innumerablesuch arrangements and is intended to be merely representative of onesuch arrangement. As should be understood, the number of light sources10, 210 on each rail and the length of each rail may be varied as may bedesired in order to contain any type, configuration, location, numberand/or arrangement of light sources 10, 210 on each rail, and the lengthof each rail may also be varied so as to be longer or shorter in length,as desired.

Referring to FIGS. 16A-16F, an example embodiment is shown of case 55having front and rear facing light rails. In particular, FIGS. 16A-16Cillustrate respective back, front and perspective views of the case 55having front light rails (containing light sources 10 and light covers20) and rear facing light rails (containing light sources 210 and lightcovers 220); FIGS. 16D and 16E illustrate cross-section views of thecase 55 taken along lines 16D-16D of FIG. 16A, according to differentexample arrangements of front and rear facing light rails; and FIG. 16Fis a cross-section view of the case 55 taken along lines 16F-16F of FIG.16B, illustrating electrical connections of components of the case 55.

The illumination device 1 takes the form of a case 55 and is shownwithout the handheld computing device 100 attached thereto. Generally,the embodiment has a front side 110, back side 115, top 105, bottom 95,and at least two side surfaces 90. The case 55 includes aperture 135 toprovide unrestricted or uninhibited access for a rear facing camera ofthe computing device 100. Each rear light rail includes light sources210 having light covers 220 that are separately disposed over respectivelight sources 210. Each front light rail includes light sources 10having light covers 20 that are separately disposed over respectivelight sources 10.

Light sources 210 may be the same as light sources 10 except that lightsources 210 are arranged on the back side 115 of the case 55. Lightcovers 220, similar to light covers 20, are configured to diffuse light.Light covers 220 may be the same as light covers 20 except that lightcovers 220 are disposed on back light sources 210. In some examples,light sources 10 and 210 may have the same light characteristicproperties (e.g., producing the same colors). In some examples lightsources 10 and 210 may have different light characteristic properties(e.g., producing different colors and/or differing shades of light). Insome examples, light covers 20 and 220 may have the same properties(e.g., same material, same color, same tint). In some examples lightcovers 20 and 220 may have different properties (e.g., differentmaterial, different color, different tint). In some examples, rearfacing light rails (light sources 210 and light covers 220) may beconfigured to provide more light and/or more diffusion than front lightrails (light sources 10 and light covers 20), such as to provideimproved captured images of groups of people with a back camera comparedto “selfies” taken with a front camera.

In some examples, the forward facing light sources 10 and rear facinglight sources 210 may be independently controlled, such as by touchsensitive button 80. Thus, rear facing light sources 210 may be turnedon/off as necessary, and the case 55 may enable the same functionalityto occur for the rear facing light sources 210 as described herein withrespect to the forward facing light sources 10.

In FIGS. 16A-16E, the light sources 10, 210 (and respective light covers20, 220) are illustrated as being disposed along the length of the sidesurface(s) 90. In some examples, the light sources 10, 210 (andrespective light covers 20, 220) may fully encircle the case 55, In someexamples, the light sources 10, 210 (and respective light covers 20,220) may also be disposed along a length of the top 105 (as shown inFIG. 1) or may be disposed along a length of the bottom 95 of case 55.

In some examples, the case 55 may include charging port 85, as describedabove. In some examples, the case 55 may include an external memory slot222. The memory slot 222 may provide uninhibited access to a memory cardinterface of the handheld computing device 100. The memory slot 222 maybe suitable for accepting any suitable external memory card known in theart, such as, but not limited to, a secure digital (SD) memory card.

Referring to FIGS. 16D and 16E, two example arrangements of forward andrear facing light sources 10, 210 are shown. FIGS. 16D and 16E alsoillustrate the arrangement of rear facing light covers 220 with respectto light sources 210. For convenience, light covers 20 are not shown inFIGS. 16D and 16E. In FIG. 16D, forward light sources 10 and rear facinglight sources 210 are disposed on PCB 260 such that light sources 10,210 are aligned with each other (across PCB 260). In FIG. 16E, forwardlight sources 10 and rear facing light sources 210 are disposed on PCB260 such that light sources 10, 210 are staggered with each other(across PCB 260) (i.e., not aligned). It is understood that FIGS. 16Dand 16E represent example forward and rear facing light sourcearrangements, and that other arrangements are possible.

FIG. 16F demonstrates an example electronic connection arrangement ofsome of the components of the case 55 shown in FIG. 16B (as well as thecase shown in FIG. 17B). As shown, there is generally a front side 110,a back side 115, and a side surface 90 which services to form a recessfor receiving the computing device 100. Emanating or rising from thefront side 110 is the light covers 20. Emanating from the back side 115is the rear facing light covers 220.

Internally, the PCB 260 is shown with a rechargeable power source 30coupled thereto. Power connectors 40, such as wiring, couples theforward facing light sources 10 and the rear facing light sources 210 tothe power source 30. The depressible button 80 can function to alter anoperative state of the forward and rear facing light sources 10, 210,including, for example and without limitation, to turn light sources 10,210 on/off as well as change the luminous output of the light sources10, 210 (including independent control forward and rear facing lightsources 10, 210).

Referring to FIGS. 17A-17D, another example embodiment is shown of case55 having front and rear facing light rails. In particular, FIGS. 17Aand 17B illustrate respective back and front views of the case 55 havingfront light rails (containing light sources 10 and light covers 20) andrear facing light rails (containing light sources 210 and light covers220); and FIGS. 17C and 17D illustrate cross-section views of the case55 taken along lines 17C-17C of FIG. 17A, according to different examplearrangements of front and rear facing light rails. For convenience,light covers 20 are not shown in FIGS. 17C and 17D.

The case 55 shown in FIGS. 17A-17D is the same as the case 55 shown inFIGS. 16A-16E, except that the configuration of the light covers 220 maydiffer from the light covers 220 shown in FIGS. 16A-16E. In FIGS.17A-17D, the rear facing light covers 220 may cover more than one lightsource. For example, the light covers 220 may take the form of acontinuous “light strip” or a “light pipe” (as described above withrespect to light covers 20) which may simultaneous cover all lightsources 220 of the respective rear light rail.

As discussed above, light sources 10 (210) may be mounted to the case 55by any means that allows secure attachment, and may also be designed insuch a way that allows the light sources 10 (210) to illuminate to adirection not generally perpendicular to the front side 110 of thehandheld computing device 100. FIG. 18A-FIG. 19D illustrate exampledifferent mounting positions of the light sources 10 in case 55. FIG.18A-FIG. 19B illustrate example side-surface-facing light sources 10.FIGS. 19C and 19D illustrate example front-side-facing light sources 10.Although FIG. 18A-FIG. 19D illustrate examples of front facing lightrails, it is understood that the example design may also be applicableto rear facing light rails and a combination of front and rear facinglight rails.

In particular, FIG. 18A is a cutaway view of case 55 taken from thefront side 110 with a portion thereof removed (including the lightcovers 20) exposing the light sources 10 residing therebelow; FIG. 18Bis a cross-section view of case 55 shown in FIG. 18A along lines18B-18B; FIG. 18C is a cross-section view of portion 18C shown in FIG.18B; FIG. 19A is a cross-section view along lines 18B-18B of the case 55shown in FIG. 18A with the portion included (i.e., including lightcovers 20); FIG. 19B is a cross-section view of portion 19B shown inFIG. 19A; FIG. 19C is a cross-section view taken from the bottom side ofanother case 55 (such as shown in FIG. 13); and FIG. 19D is across-section view of portion 19D shown in FIG. 19C.

As shown in FIGS. 18A-18C, the case 55 may include light sources 10mounted on PCB boards 161. Each PCB board 161 may be mounted to the case55 parallel to side surface 90 (via attachment to the back side 115),such that the PCB board 161 extends perpendicular to front side 110.Light sources 10 may be mounted on each PCB board 161, such that thelight sources 10 (in an emitting direction) face the side surface 90,thus forming side-surface-facing light sources 10. As shown in FIGS. 19Aand 19B, light 224 from light source 10 may be emitted through lightcover(s) 20 in a direction not generally perpendicular to front side 110of the case 55.

In contrast, in FIGS. 19C and 19B, light sources 10 may be mounted onPCB board 163. Each PCB board 163 may be mounted to the case 55 parallelto side surface 90 (via attachment to the side surface 90), such thatthe PCB board 163 extends parallel to front side 110. Light sources 10may be mounted on each PCB board 163, such that the light sources 10 (inan emitting direction) face the front side 110, thus formingfront-side-facing light sources 10. As shown in FIGS. 19C and 19D, light226 from light source 10 may be emitted through light cover(s) 20 in adirection generally perpendicular to front side 110 of the case 55.

In addition to allowing the light sources to generate light 224 in adirection away from perpendicular (relative to the front side 110), asshown in FIG. 19B, side-surface-facing light sources (shown in FIGS. 19Aand 19B) may also allow the case 55 to be formed with a more compactwidth profile (i.e., between side surfaces 90) than the case 55 shown inFIG. 19C, because of the perpendicular arrangement of PCB boards 161 tofront side 110.

As discussed above, the case 55 may include power source 30 that isseparate from the internal power source of the handheld computing device100, Referring next to FIGS. 20A and 20B, example embodiments of case 55having power source 30 are described. In particular, FIGS. 20A and 20Bare perspective view diagrams of case 55 taken from the back side 115according to different example embodiments. In FIGS. 20A and 20B, thecase 55 is shown without the handheld computing device 100 coupled tothe case 55, for convenience in describing aspects of powering theillumination device 1. It is understood that FIGS. 20A and 20B representexample embodiments illustrative as to the position and arrangement ofthe case 55 and the power source 30. The power source 30 may be locatedat other positions.

Referring to FIG. 20A, the case 55 may include power source 30 (alsoreferred to as battery 30) disposed in a chamber (not shown) of case 55and secured by cover 242 attached to back side 115 of case 55. The case55 may also include depressible or touch sensitive light operationbutton 242, depressible or touch sensitive charging button 244, chargingport 248 and discharging port 250. In some examples, the case mayinclude charging indicator 246. In some examples, the case 55 mayinclude external memory slot 222. In some examples, the case may includecharging sensor 252.

In some examples, battery 30 may be permanently fixed in case 55. Insome examples, battery 30 may be removably disposed in case 55. Asdiscussed above, in some examples, battery 30 may be a disposablebattery or a rechargeable battery or any other power source, such assolar.

Battery 30 may provide power to the light sources 10. Battery 30 mayalso serve as a backup power source to the handheld computing device100. For example, with control circuitry and electrical connections(such as via dock 60 shown in FIG. 1), battery 30 may be used todirectly provide energy to the handheld computing device 100, enabling alonger overall battery life. When the battery 30 is rechargeable, thehandheld computer device 100 may also be recharged, enabling aconvenient solution for supplying power to both the illumination device1 and the handheld computing device 100.

In some examples, the case 55 may include depressible or touch sensitivebutton 242 to control an operative state of the light sources 10 (e.g.,powering light sources 10 on or off, changing a luminous output of lightsources 10, viewing angle, color, lighting patterns, etc.). Thefunctions of button 242 may be similar to touch sensitive button 80and/or illumination device switch 70 as described above.

In some examples, the case 55 may include depressible or touch sensitivebutton 244 to control charging of the internal power source of thehandheld computing device 100 by the power source 30. In some examples,button 244 may also control charging of an external device by powersource, via discharging port 250. For example, depressing or touchingbutton 244 may cycle through preset operation states, such as chargingbattery 30 via charging port 248, charging the internal power source ofthe handheld computing device 100 via charging port 248, charging theinternal power source of the handheld computing device 100 via battery30, discharging the battery 30 to power an external port via dischargingport 250 and disabling charging/discharging of battery 30. In someexamples, the functionality of button 244 may be combined with thefunctionality of button 242 into a single depressible or touch sensitivebutton.

In some examples, the case 55 may include charging indicator 246, suchas a charging bar. Charging indicator 246 may include a battery meterthat measures the battery life of power source 30 and may indicate thebattery life remaining. Charging indicator 246 may also indicate to theuser to change batteries or recharge battery 30 when necessary.

In some examples, the case 55 may include dedicated charging port 248,which may be operably coupled to power source 30 and the internal powersource of the handheld computing device 100. The charging port 248 maybe any type of suitable port including those known in the art such as aUSB port, which provides for charging power source 30 and the internalpower source of the handheld computing device 100. In some examples, thecase 55 may also be configured to be wirelessly charged (also referredto as inductive charging). For example, the charging port 248 of case 55may include an induction charger (having an induction coil) configuredto be inductively coupled to a charging station (having its owninduction coil), such as (without being limited to) a wireless chargingpad. The induction coils in the induction charger and the chargerstations may be inductively coupled to create an alternatingelectromagnetic field. The alternating electromagnetic field may beconverted into an electric current by the induction charger of the case55, to charge power source 30. In some examples, the induction chargermay use resonant inductive coupling. In some examples, charging port 248may include an induction charger in addition to a USB charging port.

In some examples, the case 55 may include dedicated discharging port 250(separate from charging port 248), which may be operably coupled topower source 30. The discharging port 250 may be any type of suitableport including those known in the art such as a USB port, which providesfor charging a downstream port (e.g., an external device) via powersource 30.

In some examples, case 55 may include charging sensor 252 forcontrolling charging of the power source 30 and the internal powersource of the handheld computing device 100. For example, chargingsensor 252 may include suitable circuitry and electrical connections tomeasure a battery life remaining for each of power source 30 and theinternal power source of the handheld computing device 100. Depending onthe measured remaining battery life, charging sensor 252 may distributeenergy received via charging port 248 among one or more of power source30 or the internal power source, based on one or more predeterminedconditions (such as prioritization of computing device charging overpower source 30 charging). For example, charging sensor 252 may permitpower source 30 to receive energy when there is greater than 80%internal battery life remaining. In contrast, charging sensor 252 maydistribute energy to the internal battery when there is less than acertain percentage of internal battery life remaining, such as 20%internal battery life remaining. The one or more predeterminedconditions for charging power source 30 and the internal battery may bepreset by the illumination device 1 and/or may be selected by the user.

Referring to FIG. 20B, the case 55 may include power source 30 (alsoreferred to as battery 30) disposed in a chamber (not shown) of case 55and secured by cover 242 attached to back side 115 of case 55. The case55 may also include depressible or touch sensitive light operationbutton 242, depressible or touch sensitive charging button 244 andcharging/discharging port 254. In some examples, the case may includecharging indicator 246, In some examples, the case 55 may includeexternal memory slot 222. In some examples, the case may includecharging sensor 252.

The case 55 shown in FIG. 20B is the same as the case 55 shown in FIG.20A, except that the case 55 in FIG. 20B includes charging/dischargingport 254 instead of separate dedicated charging port 248 and dischargingport 250. Charging/discharging port 254 may provide for both chargingpower source 30 and the internal power source of the handheld computingdevice 100, and charging downstream ports via power source 30.Charging/discharging port 254 may be any type of suitable port includingthose known in the art such as a universal serial bus (USB) port and/oran induction charger (for wireless charging). In some examples, case 55may include an induction charger in addition to a USB-typecharging/discharging port.

Although the case 55 is shown in FIGS. 20A and 20B as including externalmemory slot 222, these represent example embodiments. In some examples,the case 55 may not include external memory slot 222. Although the case55 that is shown in FIGS. 20A and 20B does not include light source(s)210 and light cover(s) 220, these represent example embodiments. In someexamples, the case may also include light source(s) 210 and lightcover(s) 220, as shown, for example, in FIG. 16A-FIG. 17D.

As discussed above, the case 55 may be a one-piece structure or mayinclude a multi-piece design, for secure attachment of the handheldcomputing device 100 to case 55. Referring next to FIG. 21A-FIG. 24F,example embodiments of case 55 configured as a two-piece structure aredescribed.

It is understood that FIG. 21A-FIG. 24F describeexample two-piece case designs, and that the invention is not limited tothese examples. It is also possible that the handheld computing device100 may be fastened to the case 55 with other means such aspre-positioned screws, hook-and-loop fasteners, riveting, or any otherkind of mechanisms allowing a secure attachment. In some examples, thecase 55 is removably attached to the handheld computing device 100,allowing easy detaching for higher level of flexibility. In someexamples, the case 55 may be a permanent fixture of the handheldcomputing device 100, for example, to provide a high level ofintegration between the handheld computing device 100 and theillumination device 1.

The first section 290 may be pivotablydetached from the second section 294 by decoupling protrusions 292 fromrecesses 296. In operation, for example, the handheld computing device100 may be coupled to front side 110 of second section 264, with firstsection 290 pivotably detached from recesses 296 of second section 294.Next, first section 290 may be pivotably coupled to second section 294,thereby securing the handheld computing device 100 to case 55.

In some embodiments, the illumination device may implement shockabsorbing features designed to protect the computing device from falls,shaking, and the like. In other embodiments, a covering such as a glassor acrylic may overlay the computing device's display to prevent similarharm to the display of the computing device. In yet other embodiments,the light sources may flash, strobe, or otherwise be used to signifythat an emergency is occurring or to otherwise garner attention fromanother. In other embodiments, a “selfie stick” or other apparatus maybe coupled to the illumination device to provide flexibility in use. Insome embodiments, the illumination device may have slots for cash,credit cards, debit cards, and the like. Even still, in otherembodiments there may be an integrated battery and/or signal boosterwhich can provide extended battery life and enhanced signal quality whennecessary.

As indicated above, it is in the purview of the current invention that aseries of computer applications or programs may accompany theillumination device disclosed herein. These applications may facilitatethe use of the illumination device and ensure that it is safe,well-controlled, and optimized to assist the use of some otherapplications.

For example, when the illumination device is sufficiently connected andsynergized with the computing device, a program may be used tospecifically control the light source of the illumination device toadjust the luminous intensity, viewing angle, color, and lightingpattern of the light source. A user of a handheld computing device mayturn on the illumination device simply to provide general illumination.A handheld computing device, in such situations, may be used as aflashlight in a dark place. When the illumination device is equippedwith an ambient light sensor, as indicated above, it is possible to havea program that automatically adjusts the luminous intensity of the lightsource based on ambient light conditions.

Another example is a video call program that specifically integrates theusage of the illumination device. Before the user transmits his/herimage, he/she may view the image on the display screen to obtain optimalresults. The program may control both the camera and the illuminationdevice, allowing easy adjustment without switch to another program thatcontrols the camera. The program may facilitate this process by settingcertain criteria that help the user to optimize the image. For instance,the program may display on the screen a dotted-line contour of a generichuman face, while the user of the handheld computing device may adjustthe distance of his/her face to the device and/or the zoom and focus ofthe front camera to make the image of his/her face to fit thedotted-line contour, achieving optimal results. A slight variation ofthis design is to display a generic eye contour that allows the user tomake adjustment to match his/her image to the contour. Or the programmay directly show suggestions or recommendations on the display screento urge the user to turn the illumination device on, make it brighter ordim it, or to adjust the zoom and/or focus of the camera for optimalimage. In essence, the illumination intensity may be adjusted accordingto the optimal focal length of the camera. Such a basic design shouldalso be applicable to other programs. Similarly, a photo or videocapturing program having the same features may be installed to assistthe use of the illumination device. The photo or video capturing programmay aid the user in adjusting the illumination device to obtain the bestresult as to picture quality.

Another example is a “makeup mirror” application that integrates theillumination device with the front camera. In some cases, a user of ahandheld computing device would like to see his/her own image to becaptured by the front camera and be displayed on the display screensimultaneously. The user then would be able to assess his/her appearanceand make necessary adjustments. To achieve optimal results, the “makeupmirror” application would allow the user to control the luminousintensity, viewing angle, color, and lighting pattern of the lightsource in the illumination device, or such features may be adjustedautomatically by the application when the ambient light sensor isincluded and used. Combined with the frame stand or hanger structurethat may be a part of the attachment assembly, the user may set thehandheld computing device in an upright position without actuallyholding the device, freeing up both of the user's hands for optimalmaneuvering, while the whole process is being conducted under idealillumination.

Also indicated as above, the illumination device may serve as indicatoror signaling source for the status of the handheld computing device. Forexample, when there is an incoming call to a small phone, a handheldcomputing device, the light source of the illumination device may lightup or change the luminous intensity, viewing angle, color, and/orlighting pattern of the lights. The lights may flash or subsections ofthe lights are turned on rotationally. A more complex set up may allowthe user of the smart phone to establish and manage specificprofiles—specific combination of luminous intensity, viewing angle,color, and/or lighting pattern—for the illumination device. The user maychoose different profiles to match different callers. Such anapplication controls the illumination device in somewhat similar ways asring tones are managed for smart phones, further enriching the userexperience.

Furthermore, since the illumination device may be used as signals forthe computing device to which the illumination device is connected, itis possible that the illumination device may be integrated with otherprogram or application being used by the computing device. For example,it is possible to set up the illumination device that when a certaingame is being played, the illumination device is turned on and theluminous intensity, viewing angle, color, and/or lighting pattern of thelights change with the progress of the game. A similar implementation isalso possible for music. Certain light profiles may be integrated withthe music program on the computing device, allowing the lights to flashrhythmically, for example, when the music is being played.

Although this invention has been described with a certain degree ofparticularity, it is to be understood that the present disclosure hasbeen made only by way of illustration and that numerous changes in thedetails of construction and arrangement of parts may be resorted towithout departing from the spirit and the scope of the invention.
